Jacques and george meet in the middle of a lake while paddling in their canoes. they come to a complete stop and talk for a while. when they are ready to leave, jacques pushes george's canoe with a force f to separate the two canoes. what is correct to say about the final momentum and kinetic energy of the system if we can neglect any resistance due to the water?

i believe it is b. what was the cause of the big bang

hope this !

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
